To all whom zit may concern.-

Beit known that I, SAMUEL A. COFFMAN, a

lcitizen of the United States, residing at Marietta, in the county oflVashington and State of Ohio, have invented a new and use'l'ulMattress-Stuffin g Machine, ot' which the following is a specification.

This invention relates to mattress stuffing machines, and has Vfor itsprincipal object to provide a machine by which the Yfilling material maybe subjected to any desired degree of pressure and forced bodily intothe tick.

A i'urther object of the invention is to provide a machine of thischaracter that can be readily adjusted in order to term mattresses ofany width.

A still further object of the invention is to provide a machine of suchconstruction that the width of the stuffing receiving chamber, thespout, and the plunger may all be altered simultaneously.

A still further object of' the invention is to provide -a novel means`for raising and lowering the lid of the stuffing box, and further toprovide improved means for forcing the lid down to closed position tocompress the stuHing material and hold the same under pressure whilebeing Vforced into the tick.

Further objects of the invention are to improve, simplify and cheapenthe construction'o'f machines of this type, and to so arrange them as topermit of ready manipulation.

/Vith these and other objects in view, as will more Yhilly hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts, hereinafter vfully described, illustrated inthe accompanying drawings, and particularly pointed out in the appendedclaims, it being understood that various changes in the form,proportions, size and minor details of the structure may be made withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the accompanying drawings Figure 1 is a longitudinal sectionalelevation of a mattress stuffing machine constructed in accordance withtheinvention. Fig. 2 is a transverse sectional view of the same on theline 2 2 of Fig. 1. .Fig 3 is a similar view on the line 3 3 of Fig. 1Fig. L is a transverse section on the line 4 4 ol Fig. 1. Fig. 5 is adetail perspective view of the head of the plunger. Fig. 6 is a detailperspective view of the spout.

Similar numerals el reference are 4employed to indicate correspondinglparts throughout the several figures of the drawings.

The working parts of the machine are supkported on a suitable frame 10which may be formed of wood or metal, and at the top of which is ahorizontally disposed bed or table 11. The top of the central portionof" the table' is covered by a metallic plate 13 which extends from therear end of the compression chamber out to the discharge end of thespout, this plate being` permanently secured in place. At the oppositesides of the table are arranged vertical plates 16, to the lower edgesel which are secured the vertical 'flanges of metallic plates 17, theedges of which overlap the edges of the plate 13, these plates beingextended out to the discharge end of the spout, as shownin Fig. 6.Connected to the side walls 16 are the vertical arms 1S of two sets ofrack bars 19, cach set of rack bars being mounted in suitable guidesbelow the table 11, and being engaged by a pinion 20. The two pinionsare mounted on a shaft 21 that is adapted to suitable bearings carriedby the-'frame and is provided at one end with a bevel gear 22 whichintermeshes with a similar bevel gear 23, the latter being carried by atransversely disposed shaft 24 that is provided at one end with a handwheel 25 which may be turned for the purpose et operating the shaft andmoving the side plates toward or from each other for the purpose ofvarying the width oi the compression chamber and the discharge spoilt.

At a point above the rear end of the compression chamber is atransversely disposed rod 26 on which is pivoted the lid or cover 27 ofthe compression chamber. This lid or cover comprises a central web 2S,the lower vface of which is sheathed by a strip olt metal 29 and theplate 2S is reinforced at each edge by longitudinal bars B0. At eachside of the lid or cover is a har 31 carrying a plate 32 provided with ametallic sheathing 33, and the end ol each plate 32 is provided with anangularly bent arm 34 which extends up over the plate 2S in order thatthe side plates may IOO be properly supported, and yet be free to slidetoward and from each other as the width of the compression chamber isvaried.

Projecting from the side bars 31 are small metallic loops 34 which arearranged near the opposite ends of the side plates, and which extendover pins 35 that are carried by the side plates 16, the constructionbeing such that when the side plates 16 are adjusted toward and fromeach other, the corresponding portions of the cover will be similarlyadjusted. Vhen the cover is adjusted, the parts are locked in place by athumbnut which engages a pair of slotted bars 41 carried by the sidebars 3 1 and extending inward over a screw 43 that is carried by a shortpost or block 44 on the center plate 2S.

The rod l26 forms a pivot on which the rod or cover may be swung to openor closed position, and for this purpose a cable 45 is employed, thecable being connected at one end to the lid or cover, and being securedat the opposite end to a cross bar 46 that is carried by a plurality ofvertically disposed bars 43 that constitute a part of the frame of themachine, the cable passing over a stationary sheave 49, and ruimingsheave 50.

The running sheave 50 is carried by a bracket 51 that has a threadedopening for the reception of a vertically disposed screw 52 supported bythe frame, and the opposite sides of the bracket are provided with arms53 which engageagainst two of the bars 48 for the purpose of preventingrotative movement of said bracket. The lower end of the screw 52 isprovided with a bevel gear 54 which is engaged by a pair of bevel gears55, both of which are mounted loosely on a transversely disposed` shaft56 that is carried by suitable bearings on the-frame. Mounted loosely onthe shaft 56 is a pair of pulleys 58, one of which is driven by astraight belt and the other by a crossed belt, so that the pulleysrotate in opposite directions, respectively, and clutching` members 59are introduced between the pulleys and the bevel gears, so that one orother of said bevel gears may be rotated for the purpose of turning thescrew and causing the travel of the nut 53 along said screw, and in thismanner moving the cover to open or closed position.

` l/Vhen the cover is moved down to closed position, pressure may beexerted thereon by a pair of rack bars 60 that are mounted in suitableguides formed in posts 61 near the discharge end of the machine. Each ofthese racks has a rearwardly extending lug 62 arracks and release thecover, so that the latter I may be moved to open position when a newsupply of material is to be inserted in the compression chamber.

The lower portion of the spout, which is formed of the plates 13 and 17has been already described. The upper section is formed of three plates70, 71 and 72, of which the central plate is secured to a pair of crossbars 73 carried by a pair of blocks 75 that are provided with verticalslots 76 through which pass screws 77, the latter being engaged by thumbnuts 78 which may be turned for the purpose of locking the blocks inadjusted position, this construction permitting the adjustment of thevertical height of the spout. The side plates 71 72 are provided with'lianges at their rear ends, which ilanges S0 iit between the cross bars73 in such manner as to permit lateral movement of the plates 71 and 72for the purpose of altering the width of the spout. These side plates 71and 72 are provided with projecting arms 81 having openings for thereception of pins 32 that are carried by the vertical fianges of theside plates 17, so that as said side plates 17 are adjusted, the upperplates 71 and 72 will, also be adjusted, and the width of the spout willthus be altered simultaneously -With the width of the compressionchamber.

The plunger is provided at its forward end with a pair of overlappingplates 91 each of which is provided with a slot for the reception of aguiding bolt 92 that extends into the main body of the plunger. Thelocking bolt 93 also passes through both slots and is provided with athumb nut 94 by which the plates may be locked in adjusted position. Theouter ends of the plunger plates are provided with rearwardly bentportions which in one position engagewith arms 95 that are carried bythe side plates 16 of the compression chamber, these arms being lockednear the rear ends of the bars. When the plunger is adjusted to thisposition and the width of the compression chamber is altered, the plates91 will be correspondingly moved in order that the width of the plungermay correspond to the width of the chamber, and in this manner all ofthe parts, that is to say, the compression chamber, the spout, and theplunger, may be simultaneously moved for the manufacture of mattressesof dierent width.

The plunger rod 96 extends rearward over the frame, and is guided by apair of angle bars 97 that are carried by bars 98 forming a part of theframe. The rear end of the plunger rod is connected to a link belt 09that passes over a roller to sprocket wheels 100 and 101, the sprocketwheel 101 being carried bya shaft 102 adapted to suitable bearings onthe frame. On this shaft are two loose pulleys 103, one of which isdriven by a straight belt, and the other by a crossed belt, the pulleysleading in opposite directions, respectively. Adjacent to each pulley isa clutching member 104 which may be operated for the purpose ofclutching the pulley to the shaft and thus transmitting movement to thelink belt, first in one direction and then in the opposite direction.

Between the' end of the compression chamber and the plunger is arrangeda gate 106 that is carried by a bar 107 adapted to guides 108 supportedby the frame. The opposite ends of this bar 107 are connected tothelower ends of cables 100 which pass over suitable guiding sheaves 110and are connected tothe lower end of a lever 111 that is pivoted on abracket 112 below the table of the machine. The upper end of this leveris adapted to fit within a slot 113 that is formed in the plunger rod,and when the plunger moves forward, the end wall of the slot will engagethe lever and move the same for the purpose of automatically elevatingthe gate, and then during the continued forward movement of the plungerrod, the lever will be held in engagement with the bottom of the rod,and the gate maintained in open position. iVhen the plunger moves to therear, the lever will reenter the slot and allow the gate to move down toclosed positien by gravity.

With a machine constructed in accordance with this invention, thestuffing material may be readily placed in position and subjected to anydesired degree of pressure, while the parts are so arranged as to permitrapid and simultaneous adjustment of all of the parts for themanufacture of matresses of different widths.
